SO i have four discus right now and it seems that there is an alpha and then its like a chain reaction if the other two are around one picks on the other then that one picks on another one and then down to the last one and then it chills out for a litttle and everyone does there own thing then it happens again i feel like im seeing average cichlid behavior but sometimes it gets a little aggressive considering these are discus and i was told today that five discus would'nt fit in a 55 as adults but i think it would work fine and ive heard contradicting things from other people so somebody help me out because this is my first time owning discus and arent familiar with there cichlid/group behavior. On another note everyone is getting food and no fish are cornered into the top of the tank just a little chasing every now and then but when they are worried they all pack together
